Definitions

  • the invention relates to the manufacture of partially cured resin impregnated papers or non-wovens used for decorative and industrial laminates.
  • the impregnated and optionally coated paper or non-woven is subsequently fully cured under pressure in a hot press to form a laminate.
  • the full and final curing of the laminate in a hot press while under pressure enables the b-stage pre-preg to bond with other b-stage pre-pregs, and/or a carrier substrate such as particleboard, fibreboard or oriented strand board.
  • the invention therefore also relates to laminate products manufactured using the partially cured resin impregnated papers or non-wovens formed according to the invention.
  • the optimal process technology for bringing impregnated papers or non-woven materials used in laminate manufacture to the so-called b-stage includes all of single bath, single bath and coating, and single bath and multiple coating options. "Single bath” also embraces multiple dipping in a single bath or split baths. Papers or non-wovens may be developed that only require coating of the resin onto a pretreated surface thereby avoiding the usual first bath saturation.
  • the basic option is to saturate the paper or non-woven in a bath of resin, usually urea formaldehyde (UF) resin, melamine formaldehyde (MF) resin, phenol formaldehyde (PF) resin or any combination of these, before controlling the resin pickup via a set of metering rollers.
  • the resin impregnated paper or non-woven is then passed through a set of ovens, each oven or zone set at temperatures that enable the solvent to volatilise and the resin to progress in the degree of cure.
  • the rate of progress of the paper or non-woven through the oven, and the temperature profile can be carefully controlled to prevent premature skinning of the surface through resin polymerisation in the outer layer.
  • Dusting can cover parts of equipment such as safety beams used as breakers if a worker enters a dangerous part of the machine, and a health issue inevitably arises from dust particles in the air.
  • the impregnated paper or non-woven at the end of the impregnation process has a known amount of remaining volatiles and a known degree of cure.
  • This partially dried and partially cured impregnated paper or non-woven is known as a b-stage pre-preg.
  • First is the high costs of energy arising from the set of ovens.
  • Second is the large footprint in the form of the long series of drying ovens required to achieve high operating speed.
  • US 84738868 relates to a continues process for the preparation of a metric resin impregnated fibre pre-pregs, comprising impregnating fibre reinforcing material of a solution of a thermoplastic or thermosetting plastic precursors dissolved in an organic solvent and evaporating and recovering the solvent, wherein the evaporation of the solvent is achieved by exposing pre-pregs to visible or infrared light of a waveband, which corresponds to the peak absorption frequency of the solvent
  • NIR irradiation eg applied from halogen-tube radiators
  • NIR irradiation is an effective mechanism for drying or curing a variety of systems: an early disclosure was in US patent 6,436,485 for the purpose of cross-linking and curing the powder in powder coating of thermally sensitive substrates.
  • Other disclosures of interest include WO 2004/106027 [post forming of thermosetting laminates using NIR radiation], and WO 03/000612 [curing adhesive or sealing agents using NIR radiation].
  • NIR irradiation can be usefully applied to the production of pre-pregs with significant process advantages without incurring the skinning and consequent dusting problems that might have been expected to arise with the higher drying and curing rates that can be achieved with NIR irradiation.
  • the invention accordingly provides, in a first aspect, as defined in claim 1 a method of manufacturing a b-stage pre-preg of resin impregnated paper or non-woven, which pre-preg that is suitable for inclusion in a decorative or industrial laminate, characterised by impregnating a paper or non-woven with a resin carried by a solvent, which resin includes one or more of melamine formaldehyde, urea formaldehyde, and phenol formaldehyde or any combination of these, and thereafter irradiating the resin impregnated paper or non-woven with near infra-red (NIR) radiation to partially remove solvent by evaporation of the solvent, and to advance the resin impregnated paper to b-stage cure of the resin, whereby to produce a partially dried and partially cured b-stage resin impregnated paper pre-preg suitable for subsequent further final curing in the formation of a decorative or industrial laminate
  • NIR near infra-red
  • the invention further provides as defined in claim 10, an apparatus for manufacturing a b-stage pre-preg of resin impregnated paper or non-woven, which pre-preg that is suitable for inclusion in a decorative or industrial laminate, including a resin impregnation station for impregnating a paper or non-woven with resin carried by a solvent, which resin includes one or more of melamine formaldehyde, urea formaldehyde and phenol formaldehyde or any combination of these, and a heating and curing station having irradiation means to irradiate the resin-impregnated paper or non-woven with near infra-red (NIR) radiation to partially remove solvent by evaporation of the solvent, and to advance cure of the resin the resin impregnated paper to b-stage, whereby to produce a partially dried and partially cured b-stage resin impregnated paper pre-preg suitable for subsequent further final curing in the formation of a decorative or industrial laminate.
  • near infra-red is herein meant the wavelength range between the visible region and 2.5 ⁇ m, is 0.7 to 2.5 ⁇ m.
  • NIR radiation does not rely on thermal conduction to the interior as do conventional ovens and infra-red heating systems, but is directed immediately into the whole body of the wet resin to achieve simultaneous drying and curing. As drying occurs, simultaneously the rate of curing increases.
  • a significant facility arising from the invention is the ability, in a preferred embodiment of the invention, to achieve substantially uniform application of the NIR radiation through the impregnated paper, an outcome not possible in current state of the art drying equipment.
  • a further advantage is the ability to apply the energy only across the width of the web rather than the width of the drying cabinet.
  • the NIR radiation is thought to cause flash evaporation of the solvent, which is most often water, by agitation of the solvent molecules, and to advance curing as the solvent is driven off by agitating the aminoplast resin molecules. Radiant heat from the NIR apparatus also provides energy to advance the cure of the resin.
  • the invention allows for a considerable reduction in the number of drying ovens required to achieve the desired properties of the partially dried and partially cured b-stage pre-preg.
  • NIR irradiation may be employed alone or in conjunction with conventional non-NIR drying/curing ovens to achieve a pre-determined drying and curing program.
  • the apparatus further includes means for conveying the paper or non-woven as an elongated web through the resin impregnation station and the heating and curing station.
  • the method includes controlling the amount of the resin outside the body or matrix of the paper or non-woven.
  • metering means may be provided between the resin impregnation station and the heating and curing station. This controlling may comprise substantially removing resin outside the body or matrix of the paper or non-woven.
  • the dwell time using NIR irradiation may be able to be reduced to of the order of seconds or less.
  • the amount of NIR electromagnetic radiation will vary depending on the properties of the paper or non-woven being processed.
  • a black paper will absorb more energy than a white paper or clear overlay paper, and thus the parameters for the individual paper or non-woven need to be taken into consideration.
  • Options to manage the process include controlling the speed at which the impregnated and/or coated paper or non-woven passes through the NIR radiation unit or units, controlling the power output of the NIR unit or units, choice of NIR emitter (eg 800w, 1200w, 1800w, 2500w, 3600w, 4000w and 4400w) and whether the NIR radiation is applied from one side or both sides.
  • NIR emitter eg 800w, 1200w, 1800w, 2500w, 3600w, 4000w and 4400w
  • the method may include applying one or more successive thin coats of resin to the at least partially dried and at least partially cured b-stage pre-preg produced at the heating and curing station.
  • Such thin coats may be applied at a coverage in the range 2 to 10 g/m 2 , preferably 4 to 8 g/m 2 , most preferably 5 to 6 g/ m 2 .
  • the invention provides apparatus for applying a thin coat or multiple thin coats of resin to an at least partially dried and at least partially cured b-stage pre-preg, disposed downstream of a heating and curing station or stations that produced the pre-preg.
  • the resin impregnating the paper or non-woven may be a thermosetting resin component consisting of UF, MF, PF, or any combination of these, whether or not modified with other compatible resin systems.
  • the invention extends, in a third aspect, to a method of manufacturing a decorative or industrial laminate, characterised by employing one or more b-stage pre-preg papers or non-wovens produced according to the first aspect of the invention.
  • this method may further employ in the laminate one or more pre-preg papers or non-wovens produced by drying and curing in conventional non-NIR ovens.
  • the final fully cured surface and surface characteristics may be obtained, for example, in a hot press.
  • the illustrated apparatus includes a resin impregnation station 10, and a heating and curing station 20.
  • An elongated web 5 of paper or non-woven is drawn from a roll 6 through the successive stations 10, 20.
  • Resin impregnation station 10 comprises an aqueous or other solvent resin bath 12 in which web 5 is in contact twice with the resin 11 as illustrated to ensure paper saturation, a short contact against a pre-wet roll 13, followed by a longer dip 19. Web 5 then passes to metering means 14 comprising metering rollers 15 that are adjustable to control the amount of resin outside the body or matrix of the paper or non-woven web 5. It is found that best results are achieved downstream if the metering means is set to substantially remove resin outside the body or matrix of the paper and non-woven, i.e. there is left at most only a minimal surface coating of the resin on the paper or non-woven.
  • the resin is typically melamine formaldehyde (MF), urea formaldehyde (UF) or phenol formaldehyde (FF) resin, but these may be used in combination, or any other suitable or desired resin may be employed.
  • MF melamine formaldehyde
  • UF urea formaldehyde
  • FF phenol formaldehyde
  • the impregnated paper or non-woven 5' optionally contacts a set of smoothing rolls 16 and is then passed into a treatment tunnel 22 of heating and curing station 20.
  • the impregnated paper or non-woven 5' is irradiated from both sides by respective NIR irradiator units 24, 25 for a period typically in the range 0.2 to 1.5 seconds.
  • This irradiation is effective to at least partially remove the resin solvent, typically water, by flash evaporation of the solvent, effected through agitation of the solvent molecules.
  • the NIR radiation is further effective to advance cure of the resin, for example by agitating aminoplast molecules of the resin.
  • the web 5 is moved through the successive units by a web conveying configuration of suitable form. This is not illustrated in detail but components are depicted diagrammatically at some turning points, e.g. at 17.
  • Each NIR irradiator unit 24, 25 conveniently comprises a bank of elongate NIR emitters 26 ( Figure 3 ) preferably arranged in functional blocks 28 of six emitters each.
  • the bank extends as an upper or lower bridge across the web path with the emitters aligned in the direction of web travel.
  • Each block may, for example, extend 120mm laterally of the web, with each emitter, e.g., 250 mm long.
  • the NIR emitter 26, or at least the emitter blocks 28, that lie outside the impregnated web of paper or non-woven can be turned off, meaning that the radiation is only applied on the web and not significantly outside the web, thereby increasing energy productivity. Examples of different web widths are annotated in Figure 3 .
  • the distance from the web to the emitters 26 is adjustable according to other parameters such as type of emitter, web speed and grammage or colour of the paper or non-woven material.
  • successive NIR irradiations are effected, either with separate irradiators in the one unit or at separate spaced heating and curing stations.
  • the irradiation is managed so as to convert the impregnated paper or non-woven 5' to an at least partially dried and at least partially cured b-stage pre-preg 5".
  • the pre-preg 5" is successively treated by applying one or more thin coats of the resin at coating stations 30, and then partially drying and partially curing the respective coat at further NIR drying and curing stations 20' similar to station 20.
  • Coating stations 30 may apply the coats by spraying (32) or by means of gravure rolls (34), and a thin coat is typically applied to both sides of the pre-preg.
  • the number of thin coats can be as many as is required to obtain a desired amount of final resin uptake and coat weight.
  • a typical individual applied thin coat has a coverage of the order of 2 - 10 g/m 2 , preferably 4 - 8 g/m 2 most preferably 5 - 6 g/m 2 .
  • a web of white décor paper, of basis weight 80 gsm was impregnated with melamine formaldehyde resin in aqueous solvent, and then partially dried and partially cured by being passed twice between 4.4 kw NIR irradiators at 60 m/min. With the NIR irradiators operating at 80% power, the first pass exit temperature was measured as 75°C and the final exit temperature as 102°C. The end weight (paper, resin and water) was observed to be 165 gsm including 11% volatiles. Total residence time between the NIR irradiators was 0.5 seconds.
  • NIR radiation is an extremely effective method of removing the solvent from the impregnated paper or non-woven over a comparatively short distance and with a comparatively short exposure time to the NIR energy source.
  • a conventional set of drying ovens operating at the same or a similar web speed would remove similar amounts of solvent over a distance of 12 - 20 metres with a dwell time of 18 - 30 seconds.
